c# - XAML设计器使用VS2015 RTM引发“拒绝访问”异常

我今天刚刚重新安装了Windows 10 + Visual Studio 2015和RTM。当我创建一个新的UWP应用并双击MainPage.xaml时，设计器立即崩溃。这是堆栈跟踪：

System.Exception
Package could not be registered.

error 0x80070005: While processing the request, the system failed to register the windows.capability extension due to the following error: Access is denied.

   at System.Threading.Tasks.Task`1.InnerInvoke()

我在MSDN上发现了other帖子，看起来它们具有相似的堆栈跟踪，但是有不同的错误（通常是有关损坏的程序包）。这些是否适用/是否有其他解决方法？

谢谢。

最佳答案

您必须启用Windows 10系统的“开发人员模式”才能为应用程序开发启用调试和设计器。另请参见以下站点：Enable your device for development
